Waters Corp Waters Oasis MCX Flangeless Vac Cartridge, 1 cc, 10 mg, 30 μm
These 1 cc flangeless cartridges feature a novel, mixed-mode polymeric sorbent, optimized for high selectivity and sensitivity in extracting basic compounds with cation-exchange groups. The sorbent is water wettable, ensuring consistent retention and recoveries even if it runs dry. The flangeless design allows for close packing, ideal for specialized automated SPE systems.
- Contains a novel, mixed-mode polymeric sorbent optimized for higher selectivity and sensitivity in extracting basic compounds with cation-exchange groups.
- The sorbent is water wettable, maintaining its capability for higher retention and excellent recoveries even if it runs dry.
- No need for extraordinary steps to prevent sorbent beds from drying out during critical steps prior to sample loading.
- Flangeless configuration allows cartridges to be closely packed for processing in specialized automated SPE systems.
